Building the D-Frame
Putting the D-Frame together is relatively easy – and fun. Starting with the motherboard tray (Figure 5), you need to affix the top and bottom frames (Figure 6). Then, you need to install the front and rear frames (Figure 7). By the end of this process, you have an overall idea of how the case will look.
The next step is to install the screws that will hold the glass panels. See Figure 8.
